What are the differences between the different methods of ingestion?

How should I ingest my mushrooms

Well, any number of ways. The objective is to get active chemicals
in the mushrooms working, (obviously). As most people know, to the
majority of shroom eaters, psychedelic mushrooms taste pretty bad (or
worse), especially when they're dried. They also have a texture that
causes them to get stuck in your teeth making your mouth become
uncomfortable. And the aftertaste tends to linger. Therefore, you
probably want to avoid just chewing and swallowing (although some
trippers enjoy doing it that way).

Here are some suggestions to mask or eliminate the flavor of mushrooms:

Or, you can put the shrooms in a
blender with almost any kind of juice or iced tea. The only detriment
to that method is that the blender will cause the drink to foam up. If
there's anything you don't need, it's excess gas, as mushrooms cause
enough gastric distress on their own. If you use this method, let the
mixture rest in your glass for a few minutes and scoop off the foam
before gulping the drink down.

A better way to drink your dose is to grind
your cracker-dry shrooms in a coffee grinder and stir (or use a small
bottle and shake) them into your choice of juice.
You don't need a lot of liquid. Even for a large dose, 6-8 ounces of liquid is more than enough.

The only juice you should avoid using is
carrot juice. For some reason, it's been found to negate the effects of
psilocin upon ingestion. This is not to say that once you are tripping,
carrot juice will bring you down, it probably won't, but it will
prevent you from coming up.

Most alternative recipes require the coffee
grinder method of powdering your shrooms. Once the shrooms are
pulverised into the consistancy of talcum powder, you can put them in
or on practically anything from a peanut butter sandwich to cocktail
sauce for your shrimp, to melted chocolate, which when hardened becomes "shroom chocolates".

Keep in mind that the powder-in-liquid method provides for a very fast reaction!!
You can be getting CEVs (closed-eye visuals) in as little as 6-8
minutes and the effects increase to near peak levels within 30 minutes
of ingestion using this method.
